Not perfect but as fair as WE can get. In Northern Michigan, we don't care how many cubes you have or if your running more RPM's than stock.
We don't even check your fuel anymore! But if you place first or second you get to hook
your PTO shaft to our M&W dyno. You are allowed
10 HP per 1000 lbs. of tractor weight. A 5000 lb.
tractor can't have more than 50 HP. At some of the other local pulls they have a 3 mph speed
limit. They have a speedometer riged to a horn.
If the horn blows once you must slow down till it
stops. If is blows again you are DQ'd. A truly
stock classic or antique tractor is a very rare
bird. We can't even agree on what a "stock"
tractor is, so this is our solution.

not 100% certain here(please some one correct me if I'm wrong) but horsepower is not created equal.horsepower is a mathmatical equation of torque.with rpm being the divisor.hence a tractor having 50 horsepower at 1000rpm,will have twice the torque as a tractor having 50 horsepower at 2000 rpm.If I'm right then this seems like another JD rule. if I'm incorrect please ignore me.

The power on the drawbar & pto is still 50HP. No matter what rpm & torque the engine was making to produce the 50HP.

In my part of the country (Central Minnesota) Everybody in the stock classes hooks up to the dyno before the pull, you have two chances to make the H.P. requirements. Not so sure how particular they are about RPM's as I have not pulled, I believe the rules say close to factory as possible. Everybody also goes across a scale before they hook up. Sometimes the scales are not real accurate from pull to pull. Dynos can be the same way
Most of the times the people who win are the ones that pull several times throughout the summer, they usually have figured out how to wieght the tractor versus the guy that washes his tractor and puts the duals on or whatever hoping to see how his tractor will do.

Belt it to the dyno. If there is no pulley you can pull but no trophy.

I would like to share the rules for our "Antique tractor pull"( We started 2 years ago and have had 4 pulls and about 90 machines show up per pull.) 1)1958 and older. 2) First three finishers have to Dyno in at no more than 10% over stock in RPM and HP. We have an extensive data list of Make, Model, Year ,Expected output. Everyone has a copy and knows what is acceptable. One pull per tractor per weight class. Only allowed in 2 weight classes. I actually enjoy dragging my iron down to this pull .....You know why? Because we all have a chance to win. I have pulled 4 times and finished 8th,4th,1st,and 10th. No one tractor is dominating any classes. The only people who are sore are the ones that used to like to bring their beefed up machines to the "Antique" pull and stomp on the "Stockers". Now they have to pull in "Exhibition Class" or at the other pulls that don't enforce any rules. Our attendance has went up ;not down. People actually think "Hey maybe I've got a chance" instead of " No use loading up and going down there... So and So is bringing their semi-load of 100 hp "antiques" to the pull and we know who always wins.

This is the reason both USAP and NAPTA have set up different divisions. It gives the stockers a place, the guys like me with 100hp a place and the 200hp guys a place. Works really well, we are gonna use part of the national rules this year at our antique show to seperate the tractors. You are right the attendance has come up since doing it at our regular club pulls also. So bring your stock iron to Antes Forte we have div 2 classes for yoyu and would love to have ya. art

We have rules like this in upstate NY.The 5000 lbs class has a 49 hp rating to keep the 460 farmalls out.The 6500 lbs class has a 80 hp rating to keep the 4000 deere's out.8000 to 9500 lbs classes are anything under 100 hp.11000 to 16500 lbs classes are anything over 100 hp.To go with these stock classes are enhanced classes with the same weight and hp ratings.They may not be the best rule's but they keep everybody happy.The pull usally draws anywhere from 200 to 285 hooks a year.

There is a local club in our area that has very similar rules. Instead of 10hp/1000#, they use the weight class numbers...4500# 45hp max, 5500# 55hp...and so on. The dyno doesn't seem to be used on any kind regular schedule. But the first time pullers that place seem to always get dynoed. It is funny how that is???

Those do sound like great rules for an antique class. Personally I can't think of a single antique tractor that when stock would be over 10 HP for every thousand Pound, unless it would be one of the smaller allis's. However for a farm class I don't think it would work. Personally I pull a stock 4020G. It weighs right at 8,000 pound with me on it, and it's right at 90 horse. I pull 9 and 10 thousand natural asperated, but if I were to find an 8,000 pound class,{ours jumps from 7500 to 9000}, I'd like to try it. And there are alot of more modern tractors that weigh in the 6,000 pound range with 70hp plus. However, for an antique class It sounds like wonderful rules and a way to keep it fair. It'
s nice to know that little things like balance, tires, and driver ability does still matter while tractor pulling in some parts of the country. Later on Greg H.

Sounds like the rules at a pull I went to in Ohio. There the winner was hooked to the dyno and his rpm and hp was checked. No over runs and no over hp allowed. If over, you were DQ'd and the number 2 tractor was checked. If he was legal he became the winner.

It cuts down on operating costs but makes for a rather boring pull.

I aint tryni to rock the boat or anything. but I aint sure I like those rules best as far as HP limit. THis is my own opinion I definately aint trying to start an arguement but to me pulling antique tractors is sort of like drag racing if everyone came out and just pulled tractors that were all alike it wouldnt make for fun after too long. I like it because it is a chance for you to show your know how about tractors and build the best possible tractor you can build. We build only antiques and we only do as much as we can with the parts that are there we dont even stroke any of our tractors but they are bored as far as we can make the block handle. It is part of the fun showing what a stock block can do that people dont believe. Dont have to be the best but that way you know you gave it everything you had and your winning isnt just a game of chance.

No offense but pull in another class. The stockers want to pull against other stockers.
